Ah! I know this one. At least what I was told is it's to pack the tobacco tighter so the smoke gets more concentrated. It really only needs to be done to the pack when bought, which is why you sometimes see a smoker who just bought a pack flip it upside down and beat the daylights out of it on a flat surface (this performance is how I came to ask!). I've also seen smokers do it to individual cigarettes as well for the same reason. I just don't think it does as much there.
This I've never noticed; my father, consuming a
carton a day wouldn't have had time to do so. (Not the Big C, incidentally, got him in the end, rather the Big A.) Once the lovely fashion of cigarette cases went the way of hats, canes, & many other good things, a smoker had no convenient hard surface to tap-tap against.
